从晶格模拟确定QCD低能耦合

Determining QCD Low-Energy Couplings from lattice simulations

Silvia Necco

摘要:

综述了将格点量子色动力学与手征有效理论相匹配计算QCD低能耦合的不同策略。本文在回顾了手征有效理论在π-和p-区的主要特点之后,综述了确定首阶(Sigma,F)和次首阶(l_i,L_i)低能常数的现状,特别是最近用N_f=2和N_f=2+1模拟得到的结果。

英文摘要:

Different strategies for the computation of QCD low-energy couplings by matching lattice QCD with the chiral effective theory are reviewed. After recalling the main features of the chiral effective theory in the epsilon- and p- regimes, the current status of the determination of leading order (Sigma, F) and next-to-leading order (l_i, L_i) low-energy constants is summarised, focusing in particular on recent results obtained with N_f=2 and N_f=2+1 simulations.
